US Patent No: 7864882

Method and apparatus for generating constant envelope modulation using a quadrature transmitter

---

Abstract

---

A multi-mode communication device (100) uses a quadrature transmitter (102) for transmitting both amplitude and constant envelope angle-modulated signals. For angle modulation, a separate feedback path is used from that used for amplitude modulated signal transmission. An FM receiver (136) is used to produce error signals (214, 216) used in correcting the I and Q quadrature signals (206, 208).
